Abstract (en)

[origin: WO2007132406A2] At microwave frequencies, the use of transmission lines as a design element becomes interesting due to the small wavelengths. Inductors as part of an on-chip resonator can be made with a shorted stub, which is a transmission line, shorted at the end. Placing a MIM-capacitor at the beginning of the shorted stub can make a resonator. Shielding this kind of resonator by means of vias or stacked vias enables very compact filter designs.
